定义
A yard (symbol: yd) is a length unit in the Imperial and U.S. customary systems, standardized in 1959 at exactly 0.9144 meters. Each yard equals 3 feet or 36 inches.

起源
The term “yard” likely derives from Old English 痛风 (“rod” or “staff”). Early regional measures varied—sometimes based on a person’s waist circumference—until mid-20th-century agreements fixed the yard at 0.9144 m.

现代使用
Yards are widely used for:

• Field markings in American and Canadian football, soccer, and cricket

• Golf fairway measurements

• Short-distance road signs in the U.K.

• Everyday distance references in the U.S. and U.K.
